うのは、コスト増につながり、対策が望まれている。Conventionally, as this wastewater treatment facility, a biological denitrification treatment device is generally adopted. In a biological denitrification device, oxidized nitrogen is mainly converted into nitrogen gas by the action of facultative anaerobic denitrifying bacteria under anoxic conditions. Biological denitrification equipment requires an organic carbon source as a hydrogen donor. That is, in the biological denitrification treatment apparatus, an organic carbon source is required to remove the nitrogen component (N). Therefore, since the digested liquid after methane fermentation has a reduced carbon component (C) and hydrogen component (H), the biological denitrification equipment does not perform biological deoxidation by adding methanol or the like as an organic carbon source. Performing nitrogen (Bringman method). As described above, the process of adding methanol leads to an increase in cost, and a countermeasure is desired.
